The 5 keys to a successful full-face wire brush dermabrasion include:
1) Adequate oral sedation, nerve blocks, and tumescentanesthesia.
2) The mandatory use of an aerosol spray, -30° F to -60° F tocreate temporary rigidity that negates the rubbery textureof skin and prevents skipping of the dermabrasion wheel.
3) The "triangular stretch" technique for each patch, generally4cm x 4cm. Two of the triangles are stretched by the medical assistant and one by the physician's non-dominant hand,using sterile cloth towels. The cloth towels are also usedto protect the eyes, ears, nose, and mouth during thespraying procedure.
4) Proper depth selection, with the wire brush extending intothe reticular dermis (where fine striated lines are visible)but not into the deep dermis (a ragged appearance impliesthat you have gone too deeply).
5) A wire brush is used for larger scars and/or lines, whereasa diamond fraise will penetrate less deeply.
6) Edge feathering with chemical peeling and/or the use of adiamond fraise described below.
Patient Selection: Test spots performed at least 4 weeks prior to the procedure are nearly always mandatory and help deselect the 1% of patients who might develop a scar from the procedure. They also give the patient reassurance that the procedure will be effective, generally performed on a very small scar or wrinkled area.
Preoperatively, consent is obtained, lab work is performed, and preoperative photos are taken. Prescriptions are given for antibiotics, a Medrol DosePak, and Acyclovir if there is any history of herpes simplex.
Pre-op sedation is obtained with oral Valium, Meclizine, and Oxycodone or Hydrocodone, followed by tumescent anesthesia, inserted after the performance of blocks of the supraorbital, supratrochlear, lateral zygomaticotemporal, paranasal, mental, and marginal mandibular nerves. Proper overhead lighting is mandatory, and magnification may be of benefit to the surgeon.
